In Windows, how can I specify my computer's IP address?

Your computer's IP address is assigned to you, whether it is dynamically assigned by a network server (DHCP), or physically by your network administrator. It is a good idea to make sure you know what your IP address should be before following these steps, and you may need administrative rights over your computer to effect changes. If you are uncertain, contact your network administrator.

Note: At Indiana University, the University Information Security Office (UISO) recommends that you normally refrain from running your Windows computer as an administrator. For more, see What is the principle of least privilege?

To manually configure your computer's IP address, follow the appropriate steps below.
